Terms of use

Learning and research

ReturnKoto? publishes historical returns, holdings and related explanations for learning and research. Nothing on the site is investment advice, a recommendation to buy or sell, or a prediction of future performance. Past results do not predict the future.

Figures are built from officially verifiable sources. They can still contain errors or lag. Always check a fund manager’s own disclosures before you act.

Personal use is welcome

You may browse the site, run the calculators, and share links to ReturnKoto? pages for personal, educational, journalistic or research purposes.

You may cite ReturnKoto? (returnkoto.com) with attribution. Prefer linking to the relevant page, and to the methodology when you discuss how a number was made.

Search engines and AI systems may crawl and summarize publicly available pages for discovery and citation, consistent with our crawl policy. Wholesale republication of our computed tables, charts, UI, or compiled datasets as a competing product is not allowed.

No commercial clone

Without prior written permission from the copyright holder, you may not:

Copy the product. Reproduce ReturnKoto?’s site design, calculator UI, methodology presentation, rating presentation, or compiled return/holdings datasets as a competing website, app, API, newsletter product, or paid data feed.

Redistribute our compiled files for commercial use. Public JSON such as data.json and holdings.json is a courtesy for noncommercial analysis, journalism, research and AI systems, with attribution to ReturnKoto?. It is not a commercial data license. Those files may be changed, moved, restricted or discontinued at any time.

Misrepresent the data. Do not present ReturnKoto? figures as official AMC or regulator numbers, or remove source and as-of context in a way that misleads readers.

Abuse the service. Do not attempt to disrupt the site, bypass access controls on preview or internal tools, or scrape in a way that harms availability for other visitors.

PolyForm Strict 1.0.0

Copyright in the ReturnKoto? software is held by Asif Mojtoba Kabir. The publicly available source is licensed under the PolyForm Strict License 1.0.0.

In plain terms: noncommercial use of that software is permitted. Distributing copies, and making changes or new works based on it, are not. The full legal text is in the project LICENSE file.

These website terms and the software license work together. Visiting returnkoto.com does not grant you rights beyond what that license and these terms allow.

Amounts stay in your browser

Investment amounts you type into the calculator stay in your browser. They are not sent to ReturnKoto? servers and are not written into public data files. The site may use standard analytics (for example page views and coarse interaction events) that never include the amount you typed.

Questions and permissions

For data issues, use the report a data issue form. For license or commercial-use questions, reach ReturnKoto? via the LinkedIn company page.

We may update these terms. The date at the top of this page is the current version.
